大孔树脂处理含均三嗪类化合物工业废水的试验

Using macroporous resin for the treatment of industrial wastewater containing s-triazine compound

采用大孔树脂吸附处理含均三嗪类化合物(以三聚氰酸为代表)工业废水,考察了大孔树脂对均三嗪类化合物的吸附去除效果以及活性氯对大孔树脂吸附性能的影响。结果表明,大孔树脂可有效处理含均三嗪类化合物工业废水,处理后废水中的含氮化合物浓度可降低70%左右,且能利用碱洗和酸洗的方法对其进行解吸,解吸后吸附性能变化不大,可以重复使用。大孔树脂是处理该类废水的优良吸附剂之一。

Macroporous resin has been used for the adsorption treatment of the industrial wastewater containing s-triazine compounds （melamine as a representative）. The adsorptive removing effect of macroporous resin on thes-triazine compounds,and the effect of active chlorine on the adsorption capacity of macroporous resin areinvestigated. The results show that macroporous resin can effectively treat the industrial wastewater containing s-triazine compounds. The concentration of nitrogen-containing compound in the treated wastewater can be reduced by70% or so. In addition, soda-wash and pickling methods can be used for resorption. After desorption, the change inadsorption capacity is not much. The macroporous resin can be used repeatedly. Therefore, macroporous resin is oneof the excellent kinds of adsorbent for treating this kind of wastewater.
